[交流] 翻译一段话 谢谢

Dendrodoine A, grossularines-1 and -2, metabolites isolated from the tunicate Dendrodoa grossularia, have exhibited a cytotoxic activity on L1210 leukemia cells in culture. The inhibition of DNA synthesis induced by grossularines and the plane structure of the alpha-carboline common moiety were in favor of an intercalative process for their mechanism of action. In fact, the results of viscometry, fluorescence quenching and DNA melting experiments clearly indicated the intercalative properties of grossularine-2 explained by its quasi-planar structure and the non-intercalative DNA binding of grossularine-1 explained by the presence of a bulky indole chain at the 2-position of the alpha-carboline ring.

银虫 (小有名气)

Dendrodoine A, 海鞘素-1,海鞘素-2,是由被囊动物海鞘的代谢物中分离得到的。这些化合物对体外培养的L1210白血病细胞表现出一种细胞毒性活性。由海鞘素以及α-咔啉类共有基团的平面结构引起的DNA合成抑制作用有利于一种由于它们作用机理而引起的插入过程。事实上,黏性测试、荧光淬灭以及DNA熔点测定实验的结果清晰地指出了,这种海鞘素-2的插入特性可用其准平面结构解释,而海鞘素-1非插入的结合DNA可用其α-咔啉环2位带有的大的吲哚侧链来解释。

应该勉强能看明白是中国话……
